Curls need moisture, so why are you stripping it every 12-24 hours by washing it? Stop that! Go ahead, rinse it in the shower and add conditioner to the ends. Don't shampoo every day. You don't need to, and it wrecks your hair. Rinsing alone takes out the sweat and dirt.
Once you are out of the shower, lightly towel dry the hair and use a leave-in conditioner along with a great styling aid. There are tons of choices here, but you need something to support and give hold to those curls (a great haircut really helps with this too. Find someone who knows curly hair. Cutting curly hair is a whole separate ball game and not all stylists are trained in this area). Paul Mitchell sculpting foam is one of the oldest and still best-selling products today for curls. Whether you prefer a foam, cream, gel or oil, use something great and get it in right out of the shower.
Next, don't comb it. Run your fingers through it or use a wide tooth comb. You don't want to pull and stretch out the curls. This roughs it up and starts to really get the frizz started. Once the product is in and you have de-tangled, grab your towel and scrunch. Only use a towel for this, not your hands. Your hands are going to make it frizzy. You can use a low heat dryer with a diffuser if you need to. It's best to let it air dry if you can, but you will get more volume using a diffuser. Got a date after work? Heat up the curling iron. You can polish your natural curls with a few curls added with an iron. Maybe a little tease in the crown area, some hairspray and voila - day to night hair. Wait, did I say a "little" tease? Go for it and tease it to Jesus, ladies, you have a date.
If you read all this and you're still stumped, I recommend a styling 101 course with your stylist. Reserve this time with them and tell them you need some styling tips. If they can't help, you may need to find a curly hair specialist.
Now stop fussing with frizz. Try these tips, rock your curls and enjoy your hair. Do you know how many people wish they had your curl?
